Description

  

  Elektromagnetische Vorrichtung zum Schutze gegen Überlastung elektrischer Strom  kreise, vorzugsweise für     Stromverbrauchsanlagen.       Trotz der     fortiZährenden    Verbesserungen  der gebräuchlichen Schmelzsicherungen sind  diese noch ständig eine Quelle von Störun  gen, insbesondere bei     Stromverbranchsanlagen.     Nichtfachleute scheuen oft davor zurück, die  Auswechslung unbrauchbar gewordener Er  satzsicherungsteile vorzunehmen; häufig sind  die Ersatzteile nicht zur Hand und lassen  sich auch nicht immer sofort beschaffen;  alle Schmelzsicherungen     haben    zudem den  grossen Nachteil gemeinsam, dass der Ersatz  der Sicherungen mit bemerkenswerten Kosten  und mit relativ viel Zeitverlust verbunden  ist.  



  Die vorliegende Erfindung gestattet nun,  die bei     Stromverbrauchsanlagen    benützten  Schmelzsicherungen zu ersetzen, und zwar  in einer Weise, die Ersatzstöpsel, Patronen  oder andere Ersatzteile überflüssig macht.  Die den Gegenstand der Erfindung bildende  Vorrichtung schaltet den Strom bei Über  lastung automatisch aus; das     Wiederein-          schalten    erfolgt so,     dass    ein Festhalten in  Einschaltstellung bei Überlastung ausge  schlossen ist.

   Ein bei der automatischen    Ausschaltung von einer Klinke freigegebenes  Kontaktstück kommt nämlich bei der Wie  dereinschaltung von Hand erst dann wieder  in die Einschaltlage, worin es wieder     ver-          klinkt    wird, nachdem das seine     Bewegung     bewirkende, von Hand zu betätigende Glied  vorerst ein zugehöriges zweites Kontaktstück  so weggedrückt hat, dass der Hauptstrom un  terbrochen bleibt, solange das von Hand zu  betätigende Glied nicht wieder freigelassen  wird. Die Vorrichtung ist vorzugsweise so  eingerichtet, dass das genannte     Glied    auch  zum Ausschalten von Hand benützt werden  kann.  



  Der Schalter kann ein- oder mehrpolig  gebaut werden.  



  In beiliegender Zeichnung ist ein Aus  führungsbeispiel dargestellt. '  Der     Verbrauchström    fliesst über Kontakt  feder 1 durch Feder 2 durch die Spule 3 zu  den Verbrauchern 4.  



  Die voll ausgezogenen Linien zeigen die  Vorrichtung in der Einschaltstellung. Die  Feder 2 wird durch einen Anschlag am im  Punkt 6 drehbar gelagerten Hebel 7 in die-           ser    Stellung gehalten. Bei     Überlastung    liebt  der Kern der Spule 3 den     Hebel    ? hoch und  die Feder ?     selinellt    nach recht, so den       Siromkreis    unterbrechend.  



  Zum     Wiedereinselialteii        wird    auf den       (-ntsprecliend        isolierten    Stift 8     gedrückt.,    der       rWf-,i        Absätze    aufweist.

       Dadurch    wird     zu-          f-rst        die        Feder   <B>1</B>     zveggedrüclct,        dann        die     ? in     diF#        Linscha.ltstellung    gebracht, wo       if.        vcrl@linlzt    wird.

   Nach Loslassen des     Stif-          tc-s    8     hanii    die     Feder    1     zuri9ekkommen    und  an.     die    Feder     2?    anliegen.  



  Um von Hand     auszuselialten,    wird der  Stift S nach rechts gezogen, bis die auf ihm  sitzende Scheibe 9 an die Nase des Hebels 7       stösst    und diesen hebt, wobei     dk,        Feder     frei wird und nach rechts schwingt.



  Electromagnetic device for protection against overloading electrical circuits, preferably for power consumption systems. In spite of the continuous improvements in the conventional fuses, they are still a constant source of interference, especially in the case of power incinerators. Non-experts often shy away from replacing spare parts that have become unusable; spare parts are often not at hand and cannot always be procured immediately; All fuses also have the great disadvantage that replacing the fuses is associated with considerable costs and a relatively large amount of time lost.



  The present invention now allows the fuses used in power consumption systems to be replaced in a manner that eliminates the need for replacement plugs, cartridges or other spare parts. The device forming the subject of the invention automatically switches off the current when overloaded; it is switched on again in such a way that holding it in the switch-on position in the event of an overload is excluded.

   A contact piece released by a pawl during the automatic disconnection only comes back into the switch-on position when it is switched on again by hand, in which it is latched again after the element causing its movement to be actuated by hand initially an associated second contact piece has pushed away that the main current remains uninterrupted as long as the manually operated member is not released again. The device is preferably set up in such a way that said member can also be used to switch off manually.



  The switch can be built with one or more poles.



  In the accompanying drawing, an exemplary embodiment is shown. The consumption flow flows via contact spring 1 through spring 2 through coil 3 to consumers 4.



  The solid lines show the device in the on position. The spring 2 is held in this position by a stop on the lever 7 rotatably mounted at point 6. When overloaded, does the core of coil 3 love the lever? up and the feather? selinellt to the right, thus interrupting the Sirom circle.



  To reinstall the pin 8 (-ntsprecliend isolated pin 8) is pressed, which has rWf-, i paragraphs.

       As a result, the spring <B> 1 </B> is first pressed, then the? brought to diF # Linscha.ltstellung, where if. vcrl @ linlzt is.

   After letting go of the pin 8, the spring 1 comes back and on. the spring 2? issue.



  In order to unselialten by hand, the pin S is pulled to the right until the disc 9 sitting on it hits the nose of the lever 7 and lifts it, whereby dk, spring is released and swings to the right.
